This is absolutely great gpu at a very low price. People who have low budget but want to play all latest games can go for this card. I have played Crysis2, Modern warfare 3, battle field 3, assassins creed revelations and believe me all those games ran at medium graphics without a hitch! But beware, this card wont let you play latest games in extreme graphics but older games will have no problem with high graphics. Though this card was released way back in 09 but it has enough power to run all new games that would come in another 1-2 years. No high end psu needed for this card, only normal psu of 450 watts will do, just be sure that your psu has atleast 18amp on the 12V rail. To know this you can see the ratings on the psu. And for overclocking you can crank the processor to around 640mhz without increasing the voltage of the core. If you give some extra volts to the core you can overclock a lot more till your system is stable. Get a software called EVGA PRECISION for your overclocking needs though you dont need to overclock right now but may be in the future. And yes please upgrade to the latest firmware as soon as possible from the internet. 3D capabilites of this card is good enough(it was just amazing playing crysis2 in 3d).
